Have a VFD of 45 kw, 380/480 volts. motor connected to it is of 37 kw, 380/400 volts. the FLA for the motor is 66 amperes. But once it runs through VFD it shows 76 amperes on the VFD display. similarly checked through clamp meter at motor JB, still the same readings appear.
The question is why the motor shows high current on vfd display and clamp meter though its running smoothly. kindly assist.
